Description

Technical Field

[0001] The present invention belongs to the technical field of ship rust removal, and particularly relates to a quick-replacement cleaning disk and an ultra-high pressure water jet rust removal system. Background Art

[0002] In ship docking and repair projects, rust removal and painting play a quite important role. The efficiency and quality of rust removal and painting directly affect the quality and cycle of docking and repair. The principle of high-pressure water jet rust removal is to use an ultra-high pressure water pump to generate a water jet with a pressure above 100 MPa, and utilize the impact of the ultra-high pressure water jet on the surface of the ship plate. When the impact energy of the water flow is greater than the adhesion of the rust to the steel matrix, the rust layer is damaged, and the oil stain on the hull surface is removed, so as to achieve the purpose of rust removal and cleaning. The ultra-high pressure water jet rust removal technology uses water as the material for cleaning. During cleaning, there is no dust, no damage, and no corrosion. After rust removal, the waste water is recycled and stored, and transported to land for treatment and purification until it meets the sewage discharge standard. Compared with shot blasting and peening rust removal, the high-pressure water jet rust removal technology has the advantages of no damage and no dust pollution. Compared with laser rust removal technology that does not require any processing materials, the high-pressure water jet rust removal technology has the advantage of fast rust removal efficiency. Compared with chemical rust removal methods, it has the rust removal advantages of no corrosion and no pollution.

[0003] However, due to the different surface curvatures in different parts of the ship, such as the large surface curvatures on the left and right sides of the ship. To improve the rust removal efficiency, a larger cleaning disk can be replaced; while when rust removing the surfaces of the bow and stern of the ship, the curvatures of the bow and stern are small, and using a larger cleaning disk for rust removal has poor effect. At this time, a smaller cleaning disk needs to be replaced to improve the rust removal effect. Therefore, when using high-pressure water jet rust removal, it is necessary to replace a suitable cleaning disk according to the curvature of the rust removal surface to improve rust removal while ensuring the rust removal effect. However, most of the existing cleaning disks are integrally welded. Even if a split cleaning disk is used, the replacement is relatively complicated, which greatly affects the overall efficiency. Summary of the Invention

[0004] Aiming at the problem that most of the existing cleaning disks are integrally welded, and even if a split cleaning disk is used, the replacement is relatively complicated, which greatly affects the overall efficiency. The present invention provides a quick-replacement cleaning disk and an ultra-high pressure water jet rust removal system. The first water pipe and the second water pipe are connected through a joint. When the cleaning disk needs to be replaced, first loosen the bolts between the disk body and the cleaning robot, and then press the unlocking sleeve to disassemble the cleaning disk. Then, snap the required cleaning disk into the joint. Finally, tighten the bolts between the disk body and the cleaning robot to install the cleaning disk. The replacement operation is simple, convenient and fast.

[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0025] Embodiment 1

[0026] Below in conjunction with the present invention Figures 1 - 5 , clearly and completely describe the technical solutions in the embodiments of the present invention.

[0027] The quick-change cleaning tray of the present invention is as follows: Figures 1 - 2 As shown, it includes a dish body 1, a first water pipe 2 arranged on the dish body 1, a second water pipe 3 arranged above the first water pipe 2, a joint 5 connecting the first water pipe 2 and the second water pipe 3, and a nozzle 7 arranged below the first water pipe 2. A universal wheel 11 is fixedly connected to the dish body 1 to facilitate the movement of the dish body 1 on the ship, and a shock absorber is arranged on the universal wheel 11 to reduce the impact of the uneven surface of the ship on the dish body 1 when the dish body 1 moves on the ship, reduce the damage to the quick-change cleaning dish as a whole, and make the water flow sprayed by the nozzle 7 more stable. A brush 12 is fixed below the dish body 1 to prevent the sewage from splashing outward during rust removal, and at the same time, it can brush the spreading surface to a certain extent. A motor 61 is fixed on the disc body 1, and the motor 61 is connected to the transmission shaft 63 through the first gear set 62. The transmission shaft 63 is connected to the first water pipe 2 through the second gear set 64, so that the motor 61 controls the rotation of the first water pipe 2, and then controls the rotation of the nozzle 7 under the first water pipe 2, so as to realize the rotation of the nozzle 7 when the ultra-high pressure water jet is used to remove rust on the surface of the ship, thereby enhancing the cleaning effect.

[0028] Combination Figures 3 - 4 The first water pipe 2 and the second water pipe 3 are connected with a recessed portion 21 and a protruding portion 31 that match each other. The recessed portion 21 and the protruding portion 31 are both annular and have a "V"-shaped cross section. A sealing ring 4 is provided on each side of the "V" shape of the protruding portion 31, and a groove 211 matching the sealing ring 4 is provided on each side of the "V" shape of the recessed portion 21. The cross section of the connection between the first water pipe 2 and the second water pipe 3 is "V"-shaped, and a group of sealing rings 4 are provided on each side of the "V" shape, which greatly enhances the sealing performance of the connection between the recessed portion 21 and the protruding portion 31.

[0029] A joint 5 is fixedly installed on the outer side below the second water pipe 3. Matching clamping parts 22 and clamping grooves 53 are respectively arranged at the connection between the first water pipe 2 and the joint 5. When the first water pipe 2 and the joint 5 are connected, the first protrusion 221 on the clamping part 22 is clamped in the clamping groove 53. A release block 54 is rotatably connected to the joint 5. When the first water pipe 2 and the joint 5 are connected, the release block 54 and the clamping part 22 are respectively on both sides of the clamping groove 53, and a second protrusion 541 is arranged at the position of the release block 54 facing the clamping groove 53. The size of the clamping groove 53 matches the sizes of the first protrusion 221 and the second protrusion 541, so that only one of the first protrusion 221 and the second protrusion 541 can be inserted into the clamping groove 53. When the second protrusion 541 is clamped in the clamping groove 53, the first protrusion 221 can be extruded from the clamping groove 53. A release sleeve 55 is slidably connected to the joint 5, and the lower part of the release sleeve 55 abuts against the release block 54. When the release sleeve 55 slides downward, it pushes the release block 54 to rotate, so that the second protrusion 541 is clamped in the clamping groove 53. The lower end of the release sleeve 55 is provided with a section of inclined surface, so that when the release sleeve 55 slides downward, the release block 54 rotates slowly, avoiding damage to the release block 54 caused by excessive force. Combined Figure 5 , the release block 54 and the joint 5 are connected by a torsion spring 56, preventing the gravity of the release sleeve 55 and the release block 54 from clamping the second protrusion 541 into the clamping groove 53, thereby enhancing the connection stability between the joint 5 and the first water pipe 2. A slider 51 is connected to the joint 5 through a spring 52. When the first water pipe 2 and the joint 5 are connected, the lower part of the slider 51 abuts against the upper part of the clamping part 22. When the first protrusion 221 is clamped in the clamping groove 53, the spring 52 is compressed; when the first protrusion 221 is extruded from the clamping groove 53 by the second protrusion 541, the compressed spring 52 has a thrust on the clamping part 22, facilitating the removal of the first water pipe 2 from the joint 5. The upper end of the disk body 1 is detachably installed on the cleaning robot through bolt connection, facilitating the disassembly and installation of the disk body 1 from the cleaning robot and realizing quick replacement.

[0030] The surface curvatures on both the left and right sides of the ship are large. To improve the rust removal efficiency, a larger cleaning disc can be replaced. When rust removing the surfaces of the bow and stern of the ship, the curvatures of the bow and stern are small, and using a larger cleaning disc will not achieve good rust removal effect. At this time, a smaller cleaning disc needs to be replaced to improve the rust removal effect. Therefore, when it is necessary to replace the cleaning disc during the ship surface cleaning with the quick-change cleaning disc described in the present invention, first loosen the bolt between the disc body 1 and the cleaning robot, then press down the unlocking sleeve 55 to push the unlocking block 54 to rotate. The second protrusion 541 extrudes the first protrusion 221 out of the card slot 53, and the first water pipe 2 pops out of the joint 5 under the action of the spring 52, realizing the disassembly of the cleaning disc. After disassembly, loosen the unlocking sleeve 55, and the unlocking block 54 returns to its original position under the action of the torsion spring 56. The second protrusion 541 pops out of the card slot 53. At the same time, the unlocking sleeve 55 slides upward under the action of the torsion spring 56. At this time, just snap the required cleaning disc into the joint 5, make the recessed part 21 and the protruding part 31 fit, and at the same time, the first protrusion 221 is snapped into the card slot 53. Finally, tighten the bolt between the disc body 1 and the cleaning robot, and the replacement of the cleaning disc is completed. The operation is simple, convenient and fast.
